Windows 7 install

Yes, tardy again, but the last post took a lot out of me and it has been my birthday.
Right, installing Windows 7. Last time I had a go it was the release candidate I installed on my somewhat aged AMD Athlon XP system. It went on without problem but due to memory constraints (I only had 512mb installed) there was a very annoying lag when launching programs. So I took it off. Now, some twelve months later, I've scraped some more memory together (a pair of 256mb sticks) which takes me up to 1gb and It's Windows 7 Ultimate that's been thrown on, and it was a piece of cake! I slotted the DVD in and formatted the hard drive, cos that's the kind of guy I am. Hit a couple of keys and away it went. The installation proceeded and installed 95% of the drivers I needed and following a reboot it installed the remaining 5% (mainly the Sata and motherboard drivers). That extra memory meant no more program lag and it is a joy to use again. The only Issue I had was that both my optical drives suddenly disappeared! No rhyme or reason for it , one is a Sata drive and the other a plain old Pata. They were there in device manager but not in My Computer, still missing following a reboot so I deleted them and rebooted. This time Windows told me it had found new hardware and was installing drivers for it and my Sata drive reappeared, but still no Pata! I installed a couple more programs, looked in My Computer and there it was, it had sidled back on when I wasn't looking and I still don't know why!
So, if you are thinking about installing Windows 7, go for it. It is more stable, less intrusive and boots up a bit quicker My only caveat being, make sure you have enough memory and that drivers are available for your motherboard. Oh, and back things up before you start.
